Specific embodiment
Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality
It applies example and attached drawing is cooperated to be explained in detail.
Referring to Fig. 1, this embodiment describes a kind of interlocking mechanisms applied to permanent-magnet breaker, which is characterized in that packet
Include change-over switch 1, lower bracket 2, axle sleeve 3, organization soleplate 4, upper bracket 5, unilateral bearing 6, driving lever 7, operating shaft 8, follower lever
9, rotor 10, isolation baffle plate 11, guide plate 12；
Here it please see Figure 1, organization soleplate can be generally vertically arranged, described for fixing other component based on it
Organization soleplate can be fixed or with the plate of installation permanent-magnet breaker Switch main body for one block of plate thereon.The operating shaft is worn
Organization soleplate is crossed, is arranged perpendicular to organization soleplate, one end of the operating shaft switchs this by connecting bushing and permanent-magnet breaker
A unilateral bearing is fixed in shaft linkage on body, the end of operating shaft, and the other end of operating shaft is also fixed with driving lever, actively
The other end of bar and one end of follower lever are hinged, and the other end of follower lever is also hinged with rotor, and the other end and the conversion of rotor are opened
The main shaft linkage shut drives change-over switch movement, is additionally provided with guide plate, the guide plate and mechanism on the organization soleplate
Bottom plate is vertical, and the through-hole for allowing isolation baffle plate to pass through is additionally provided on the guide plate；The isolation baffle plate passes through on guide plate
Pilot hole, then it is rotor is hinged with follower lever.By above-mentioned design, when operating shaft is rotated, permanent-magnet breaker
Switch can achieve the effect that move synchronously with the rotor of change-over switch, and the on/off switch of permanent-magnet breaker switch can pass through conversion
Switch display, for example, the electric signal on change-over switch is converted into optical signal, so that indicative function is played, such as: turn when separating brake
Changing switch, location A, red light light again；When combined floodgate, because the movement of operating shaft drives double leval jib movement, double leval jib drives conversion to open
Pass turns to B location, and green light lights.To play electrical indicative function.Play the current permanent-magnet breaker switch work shape of instruction
The effect of state, staff can be known clearly the working condition of electric switch by instruction, avoid the generation of risky operation
And casualties.
And in further embodiment, our isolation baffle plate 11 is long strip type, and one end is provided with sliding groove, follower lever
One end articulated shaft is also connect with sliding block, and the length of sliding groove is greater than the width of sliding groove, and the middle part of sliding block is narrow to be placed in
In sliding groove, the width design that end is then greater than sliding groove not falling out, and the sliding block can slide in sliding groove.Figure
2 illustrate the active state of the articulated shaft and sliding block different from the follower lever of Fig. 1, and user is driven actively by rotation process axis
When bar, the sliding block connected on follower lever can apply active force to sliding groove, drive isolation baffle plate in the vertical direction
It is moved.As shown in the figure, the other end of isolation baffle plate further includes limiting section, and the limiting section may include and other component
Reach the various parts of pairing lock or limit effect, such as bolt, buckle, latch, hook, limits the operation of interrupter
The activity of axis.Limiting section as shown in the figure is that the baffle of bending prevents user couple for covering the operating shaft of interrupter
It is operated.Interrupter is in killer switch to the safety isolated switch of electrification compartment.Pass through the setting of above-mentioned component
It prevents when breaker closing, to the non-secure operations of disconnecting switch, prevents personnel from entering live part, therefore this programme
The technical effect for improving the safety of permanent-magnetic switching breaker can be played.
In the embodiment shown in fig. 1, upper bracket 5 and the equal vertical mechanism bottom plate of lower bracket 2 are arranged, the upper bracket 2, under
Bracket 5 is located at the over and under of operating shaft 8, and the upper bracket is parallel to each other with lower bracket, is mutually interconnected by supporting plate
It connects, the bracket plate hole that operating shaft passes through is additionally provided on the supporting plate, upper and lower bracket and supporting plate are used to carry out operating shaft
It is preferably fixed, strengthen the stability of mechanism.After the assembly is completed by said sequence, driving lever assembly is being grasped by certain angle
Make on axis, fixed with circlip (not shown), unilateral bearing is installed in operating shaft after fixing driving lever, will lead
It is transferred on unilateral bearing from connecting rod (can be multiple from connecting rod), is connect after assembling with change-over switch.On above-mentioned
The design of bracket lower bracket and supporting plate can provide effective support to operating shaft 8, so that operating shaft always works in level
On face.
In our embodiment, principal and subordinate's connecting rod can be double leval jib, and as shown in the figure, unilateral bearing is arranged in operating shaft
Outside.(up and down motion) drives the movement of shaft 14 to pass through connecting bushing when please see Figure the movement of 3 permanent magnet mechanism, 13 on/off switch here
15 drive the operating shaft movement of interlocking mechanism, and operating shaft drives double leval jib movement, rotor and change-over switch main shaft on double leval jib
One end of connection drives change-over switch main axis, and mechanical signal can be converted to the electric signal on change-over switch.Meanwhile
The sliding groove and double leval jib of isolation baffle plate link, and can be moved up and down by the guiding role of the pilot hole of guide plate.Breaker
When combined floodgate, isolation baffle plate is moved downward, to play the role of blocking the operating shaft on interrupter 16, realizes isolation interlocking.When
Operating shaft in interlocking mechanism can also drive the fortune of the shaft on Switch main body by connecting bushing when moving as main movable part
Dynamic, the rotation of shaft makes permanent magnet mechanism carry out on/off switch movement.Therefore, it accidentally grasps, uses to carry out closing a floodgate when preventing manual operation
Unilateral bearing avoids combined floodgate maloperation.In the particular embodiment, when interlocking mechanism is operated manually, operating shaft is in one-way shaft
Under the action of holding (clockwise or counterclockwise) can only be moved toward a direction.Such as: it is counterclockwise separating brake direction, operating shaft is toward inverse
Unilateral bearing forced belt turn axis is past when hour hands rotate rotates counterclockwise；It is clockwise combined floodgate direction, at this time toward operation clockwise
When unilateral bearing do not stress, unilateral bearing dallies in operating shaft, be unable to drive operating shaft rotation, therefore, permanent magnet mechanism can not
Closing by hand avoids closing a floodgate and accidentally grasp.It is designed by said mechanism, the setting of unilateral bearing enables to the mechanism can be only used for
Manual brake separating operation, it is therefore prevented that manual false switching bring adverse effect.
It should be noted that being not intended to limit although the various embodiments described above have been described herein
The scope of patent protection of the utility model.Therefore, based on the innovative idea of the utility model, embodiment described herein is carried out
Change and modification or equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly
Or above technical scheme is used in other related technical areas indirectly, it is included in the patent protection model of the utility model
Within enclosing.
